Experimental Assessment of an Emotion Tracking Software Agent (ETA) for Assisting Communicative Interactions of Multitasking Users in Groupware
(Eurosis, 2011-08-22)Interactions such as discussion and negotiation in face-to-face work contexts strongly rely on non-verbal feedback. Such feedback provides indications of important negotiation states such as agreement or disagreement and ... -
Experimental assessment of clinical MRI-induced global SAR distributions in head phantoms
(Elsevier, 2019-10-05)Accurate estimation of SAR is critical to safeguarding vulnerable patients who require an MRI procedure. The increased static field strength and RF duty cycle capabilities in modern MRI scanners mean that systems can easily ... -
Experimental assessment of MRI-induced temperature change and SAR distributions in phantoms
(NUI Galway, 2017-11-14)During an MR procedure, most of the transmitted RF power is transformed into heat within the patients’ tissue resulting from resistive losses, referred to as the specific energy absorption rate(SAR) (2). The EU standardisation ... -
Experimental characterisation and computational constitutive modelling of high temperature degradation in 9Cr steels including microstructural effects
(2016-04-20)The transition from base-load to intermittent power plant operation has led to the requirement for increased knowledge and more accurate prediction of the effects of flexible loading on plant components. This thesis is ... -
Experimental characterisation and computational modelling for cyclic elastic-plastic constitutive behaviour and fatigue damage of X100Q for steel catenary risers
(Elsevier, 2018-06-21)New higher strength steels are required for deep and ultra-deepwater steel catenary risers (SCRs). In this work, the cyclic elastic-plastic-damage behaviour of X100Q, a candidate next-generation SCR material is experimentally ... -
Experimental characterisation of neural tissue at collision speeds
(International Research Council on Biomechanics of Injury (IRCOBI), 2012)Mechanical characterisation of brain tissue at high loading velocities is particularly important for modelling Traumatic Brain Injury (TBI). During severe impact conditions, brain tissue experiences a mixture of compression, ... -
Experimental characterisation of the moment-rotation behaviour of beam-beam connections using compressed wood fasteners
(Elsevier, 2021-09-16)The widespread use of energy-intensive metallic connectors and synthetic adhesives in modern timber construction has negative implications for the end-of-life disposal or re-use of the structural timber components. Therefore, ... -
Experimental characterisation, computational modelling and design tool development for fretting fatigue and wear in flexible marine risers
(2017-09-25)Fretting is a key concern in the fatigue design of the pressure armour layer of flexible marine risers, due to the combination of extreme global dynamic loading conditions and the local geometrical-tribological conditions ... -
Experimental characterization and strengthening mechanism of process-structure-property of selective laser melted 316 L
(Elsevier, 2023-03-02)Heat treatment is the most common method to relieve residual stress and to adjust tensile properties in additively manufactured material. However, the well-known strengthening factors (e.g., dislocation density, cellular ... -
Experimental development and modelling of a novel auxiliary power unit for heavy trucks
(2017-09-26)This thesis identifies the key technical requirements for a heavy truck auxiliary power unit (APU) and explores a potential alternative technology for use in a next-generation APU that could eliminate key problems related ... -
Experimental evaluation of the effective ablation zone on ex-vivo bovine liver samples
(IEEE, 2018-09-10)Microwave thermal ablation is under investigation for minimally invasive treatments. In the cases of small targets, such as adrenal glands, microwave thermal ablation is a valuable alternative to the traditional and ... -
Experimental investigation of the moment-rotation behaviour of beam-column connections produced using compressed wood connectors
(Elsevier, 2022-04-04)The widespread use of energy-intensive metallic connectors and synthetic adhesives in modern timber construction has negative implications for the end-of-life disposal or re-use of the structural timber components. Therefore, ... -
Experimental investigation of the response of a driven pile in soft silt
(National University of Ireland Galway, 2004-12-01)The paper describes the results of field tests carried out using highly instrumented piles at a very soft estuarine clayey silt deposit at Kinnegar, Belfast. The site has been used for a number of years as a geotechnical ... -
Experimental Investigation of the Response of Osteoblasts to Static and Dynamic Loading using a Modified Atomic Force Microscope
(2013-02-07)Cells and tissues continuously experience mechanical loading during daily activity. However, the mechanisms by which cells respond to mechanical stimuli are poorly understood. The focus of this thesis is to develop atomic ... -
Experimental investigation of the serviceability behaviour of a cross laminated timber floor
(NUI Galway, 2018-08-29)European timber design standards set out basic serviceability limit design criteria for single span, simply supported floors, but the rotational stiffness of the fixing system and two-way support possible with modern solid ... -
Experimental investigation on damage evolution in pre-corroded aluminum alloy 7075-T7651 under fatigue loading
(Elsevier, 2020-09-01)This paper experimentally investigates the fatigue damage evolution in pre-corroded aluminum alloy (AA) 7075-T7651 via digital image correlation (DIC) and scanning electron microscopy (SEM). Three stages of fatigue damage ... -
An experimental investigation on the biomechanics of bone fragility in type 2diabetes
(NUI Galway, 2023-10-11)Type 2 diabetic patients experience up to a 3-fold increase in bone fracture risk. Paradoxically, type 2 diabetes is associated with a normal or increased bone mineral density (BMD) when compared to non-diabetic patients. ... -
